Description

The present invention relates to a lid urging structure, and particularly to a lid urging structure suitable for opening and closing a space for a fuel filler port or an electric charging port provided on a vehicle body.

FIG. 14 is a vehicle lid device disclosed in the applicant's prior application (Patent Document 1). The lid device 7 in the figure shows a housing 1 that partitions a space for a fuel filler port, a closed position that is rotatably supported by a link member 4 with respect to the housing 1, and a closed position that closes the opening of the housing. The lid 2 that can be switched to the 2 position and the fully open position and the lid 2 are urged in the closed direction at the closed position, and when the lid 2 is rotated from the closed direction to the 2nd position, the lid 2 is urged at the 2nd position. It is provided with an urging member 6 whose direction is reversed and can be switched from the second position to the fully open position by an urging force. Further, as the lid urging structure, in particular, the link member 4 is composed of the first link 4A and the second link 4B to compactly regulate the rotation locus of the lid, or urging between both links 4A and 4B. The urging force of the member 6 is applied to prevent the lid 2 from rattling due to the urging force in the closed position and the fully open position, and when the lid is unlocked in the closed position, the push lifter 16 resists the urging force. The lid can be rotated by lifting it up a little and using your fingertips.

Japanese Unexamined Patent Publication No. 2017-47827

In the lid urging structure, when the lid is rotated against the urging force from the fully open position to the second position in the closing operation of the lid, the urging direction of the spring body which is the urging member is reversed. Since it is rotated from the second position to the closed position at once by the urging force, it collides strongly with the push lifter, and the lid is liable to flutter or generate abnormal noise. This point becomes a serious problem because a predetermined torque is secured as the torque of the spring body so that the lid does not inadvertently flutter in the closed position.

As another configuration, in the lid urging structure B in FIG. 13, the lid is switched from the closed position and the closed position to the first position in the middle of opening, and further to the second position in the opening direction and the fully opened position. The first position is the position where the lid momentarily stops when the lid is rotated from the second position in the closing direction by the urging force, or the lid is rotated from the closed position to the opening direction against the urging force. This is the position where the operating force is momentarily unnecessary. At this first position, the lid opening angle of the structure B is as small as about 10 degrees. Therefore, in the operation of closing the lid, the lid is rotated from the second position to the first position by the urging force, stops momentarily at the first position, and then is rotated to the closed position again by the urging force. As a result, when the lid opening angle of the first position is as small as about 10 degrees, the lid hits the push lifter at high speed, and abnormal noise is likely to be generated, which impairs the sense of quality.

As a countermeasure against these, the frictional resistance of the friction material, which is an elastic member or a soft material, is used to attenuate the rotation speed of the lid. However, the friction material is not stable because the mechanical properties of the friction material change depending on the wear of the surface that generates the friction force and the environmental temperature.

An object of the present invention is to solve the above problems to improve the feeling of lid opening / closing operation as compared with the conventional case, and to make a fluttering or abnormal noise when closing the lid without depending on frictional force. The purpose is to make it difficult to occur. Other purposes will be clarified in the following description.

In order to achieve the above object, the present invention specifies with reference to FIGS. 1 to 13, a housing 1 forming a space for a fuel filler port or an electric charging port inside the opening, and a link member 4 with respect to the housing. A lid 2 that is rotatably supported by 5 and is switched to a closed position that closes the opening of the housing, a first position that is in the process of opening from the closed position, a second position that is in the opening direction, and a fully open position, and the lid. Is urged in the closing direction at the closed position, and the closing direction (this closing direction is either the closed position, the vicinity of the first position between the closed position and the first position, or the first position. , Same) When the rotation operation is performed against the urging force from the second position to the second position, the urging direction is reversed and the lid urging structure is provided with an urging member that enables switching from the second position to the fully open position by the urging force. The urging member is composed of a plurality of spring bodies 6 and 7 arranged between the link member and the housing, and the lid 2 is placed in the first position from the closed position by the balance of the spring bodies. It is characterized by adjusting the operating force that rotates against the urging force to the vicinity of the first position or the urging force that urges the lid to rotate from the vicinity of the first position or the first position to the closed position. There is.

Here, the lid urging structure of the present invention switches by rotation from a closed position in which the lid closes the opening of the housing, a first position in the middle of opening from the closed position, a second position in the opening direction, and a fully open position. Be done. This point will be described with reference to FIG. In FIG. 13, the structures A to C1 are notations in which the lid urging structures A to C1 are omitted. FIG. 13 shows a structure A using two spring bodies 6 and 7 as the product of the present invention, a structure B using a single spring body 6 as a comparative product, and a structure using a single spring body 7 or a spring body 7A. This is a test example when the lid opening angle (deg) and the lid tip operating force (N) are examined for C or C1. The lid urging structure A is an invention as in the form example. The lid urging structures B, C, and C1 are comparative products different from the morphological example in that they are composed of a single spring body.

Of these, in the structures C and C1, the lid is switched from the closed position and the closed position to the second position in the middle of opening and the fully open position as in Patent Document 1. In this structure, in the closing operation of the lid, when the lid is rotated against the urging force from the fully open position to the second position, the urging direction of the spring body is reversed and the spring body is attached from the second position to the closed position. Since it is rotated at once by the force, it strongly collides with the push lifter 16 of Patent Document 1. This point becomes a big problem when a predetermined torque is secured as the torque of the spring body so that the lid does not inadvertently flutter at the closed position (Problem 1 of the present invention).

On the other hand, in the structures A and B, the lid is switched from the closed position and the closed position to the first position in the middle of opening, and further to the second position in the opening direction and the fully opened position. Here, the second position is the same as the structures C and C1, and among the lid opening angles when the urging direction of the spring body is reversed, when the lid is operated from the fully open position to the closing direction against the urging force. This is the lid position when the urging direction of the spring body is reversed and the spring body is rotated in the closing direction by the urging force. In this example, the lid opening angle is about 50 degrees. Further, the first position is a position where the lid momentarily stops when the lid is rotated from the second position in the closing direction by an urging force, or the lid rotates from the closed position to the opening direction against the urging force. This is a position where no operating force is required when a dynamic operation is performed. At this first position, the lid opening angle is about 25 degrees for the structure A, and the lid opening angle is about 10 degrees for the structure B.

By the way, in the operation of closing the lid, in both the structures A and B, the lid is rotated from the second position in the closing direction by the urging force, then momentarily stopped at the first position, and then the urging force is again applied. Is rotated to the closed position. In this case, if the lid opening angle of the first position is as small as about 10 degrees as in the structure B, the push lifter is likely to hit the push lifter at a high speed to generate an abnormal noise, which is not easy to use and impairs the sense of quality (the present invention). Problem 2). On the other hand, in the structure A, which is an invention, the lid opening angle of the first position is greatly corrected to about 25 degrees, so that such a problem can be solved or alleviated, and fluttering and tapping noise are reduced. It is possible to increase the sense of quality and it is also effective in preventing finger pinching.

In the present invention, the lid is specified as "the first position or the vicinity of the first position from the closed position" and "the lid is the closed position from the first position or the vicinity of the first position", that is, other than the "first position". The reason for adding "near the first position" is as follows. In FIG. 13, for example, in the lid closing operation, when the lid is rotated from the second position to the first position (the lid opening angle is about 25 degrees) by the urging force of the spring body, the lid is momentarily moved to the first position. When the lid opening angle is about 20 degrees, it is urged again in the closing direction. The point is to consider the time lag associated with such reversal of the biasing direction.

It is more preferable that the above invention is embodied as specified in claims 2 to 7.
(A) The link member is composed of a first link and a second link whose one end side is pivotally supported on the back side of the lid and the other end side is pivotally supported on the inside of the housing, and the spring body is the first link and the said. The configuration includes a first spring body arranged between the housings and a second spring body arranged between the second link and the housing side (claim 2).
(B) By using the first spring body and the second spring body, the lid opening angle at the first position can be set larger than when the first and second spring bodies are used alone. (Claim 3).

(C) The configuration is provided in the housing and has a base that pivotally supports the first link and the second link and regulates the corresponding end side of the spring body (claim 4). ).
(D) The first link has an upper plate portion pivotally supported by the lid, a middle plate portion connected to the upper plate portion and pivotally supported by the base, and a width direction connected to the middle plate portion. The first spring body is arranged between the inner wall of the base provided so as to face the arm portion and the arm portion. The other end is restricted from being fitted into the fitting hole, and the other end is restricted from being fitted into the fitting hole provided in the inner wall (claim 5).

(E) The second link includes a plate body pivotally supported by the lid and the base, a pair of legs projecting below the plate body at intervals, and a back side of the leg portion. The second spring body is arranged on the inner surface side of the base, one end of which is restricted from being fitted into the groove of the one leg, and the other end of the base. It is a configuration that is provided and is restricted from being fitted into a fitting hole that penetrates in the vertical direction (claim 6).
(F) The spring body is a coil spring (claim 7). This coil spring includes a torsion spring having a winding portion.

In the invention of claim 1, when the lid is rotated from the closed direction to the second position, the urging direction is reversed at the second position and the lid urging structure can be switched from the second position to the fully open position by the urging force. As inferred from FIG. 13, when a plurality of spring bodies are used as the urging members, the lid is moved from the closed position to the first position or the first position due to the balance of each spring body as compared with the configuration of a single spring body. The magnitude of the operating force that rotates to the vicinity of the position and the magnitude of the urging force that urges the lid to rotate from the first position or the vicinity of the first position to the closed position can be optimally set, and the lid can be pulled. The feeling of opening and closing operation can be improved.

In the invention of claim 2, since the link member is composed of two links, the rotation locus of the lid can be compactly regulated as in Patent Document 1. In addition, as the lid urging structure, each link has a first spring body arranged between the first link and the housing and a second spring body arranged between the second link and the housing. It is possible to reliably prevent rattling, and as can be inferred from FIG. 13, it becomes easy to increase the lid opening angle of the first position, and the lid opening / closing operation feeling can be variously set according to the purpose.

In the invention of claim 3, when the first and second spring bodies are used, as can be seen from FIG. 13, the lid opening angle at the first position can be set larger than that of the configuration in which each spring body is used independently. Therefore, for example, in the lid closing operation, it becomes easier to alleviate the impact at the time of closing in proportion to the distance from the first position to the closing position or the rotation angle, and the conventional fluttering and tapping sound are reduced to give a high-class feeling. Can be improved.

In the invention of claim 4, by pivotally supporting each link or arranging a spring body between the lid and the base, it is possible to maintain good handleability of the lid, ease of incorporation into the housing, and appearance characteristics.

Each of the inventions of claims 5 and 6 specifically specifies the first link and the second link, and the first spring body and the second spring body based on a morphological example, and each link is simple and each. Since one end of the spring body is position-regulated to the corresponding link and the other end is position-regulated to the corresponding part of the base, assembly is easy and rattling between members can be reliably absorbed.

In the invention of claim 7, the cost can be suppressed by using a simple and versatile coil spring as the spring body.

(Operation) The operation of the lid urging structure described above will be clarified with reference to FIGS. 4 to 6 and 13.
(1) The above lid urging structure (reference numeral A in FIG. 13) is locked in a closed position where the lid 2 closes the upper opening of the housing 1 while being urged in the closing direction so as not to rattle. It is locked by means 18. When the locking means 18 is unlocked, the lid 2 is pushed in the opening direction against the urging force of the spring bodies 6 and 7 by the push 17a of the push lifter and opens slightly (in FIG. 13, the lid opening angle is large). About 6 degrees). From that state, the user picks the lid 2 with his / her hand or the like and rotates it in the opening direction against the urging force. In this process, as can be seen from FIG. 13, when the lid 2 is rotated to a little before the first position against the urging force, the spring stress is momentarily weakened because it is momentarily urged in the opening direction. It differs from the conventional one in that.

When the lid 2 is rotated to the second position (the lid opening angle is about 50 degrees in FIG. 13) against the urging force, the urging directions of the spring bodies 6 and 7 are reversed, and after that, the spring bodies It is rotated to the fully open position via the links 4 and 5 by the urging forces of 6 and 7. In this lid urging structure A, as shown in FIG. 13, the lid opening angle at the fully open position is about 118 degrees, and the lid is urged in the opening direction so as not to rattle at the fully open position. Further, this lid urging structure A is strongly urged in the lid opening direction at the fully open position as compared with the comparative lid urging structure B in which only the second spring body 6 is used as the urging member, so that the lid is fully opened. Bounce is reduced. In the lid urging structure B, the lid opening angle, which is the first position, is 10 degrees, which is the dead point of the first spring body 6. Further, in the lid urging structure C, the lid opening angle is 48 degrees, which is a dead point of the second spring body 7.

(2) When the lid 2 is closed again, when the lid 2 is rotated against the urging force from the fully open position to the second position, the urging direction is reversed at the second position, and thereafter, the link members 4 and 5 are closed. It is rotated to the first position by the urging force via. The lid 2 is momentarily stopped at the first position, and then is rotated again to the closed position via the links 4 and 5 by the urging force of the spring bodies 6 and 7. In this way, in this lid urging structure A, the lid 2 is momentarily stopped at the first position, so that the lid 2 is a comparative product that is rotated from the second position to the closed position by the urging force as in the conventional case. Compared with the urging structures C and C1, the impact force on the push lifter 16 is reduced, whereby fluttering and generation of abnormal noise can be suppressed.

Further, in this lid urging structure A, the lid opening angle of the first position is about 25 degrees due to the balance of the spring bodies 6 and 7 as compared with the comparative product B which is the first position when the lid opening angle is about 10 degrees. It's getting bigger. Therefore, in the closing operation of the lid 2, the lid 2 is rotated in the closing direction by the urging force from the second position, then momentarily stopped at the first position, and then rotated in the closing direction again by the urging force. In this process, if the lid opening angle of the first position is as small as about 10 degrees as in the comparative lid urging structure B, the push lifter 16 is likely to hit the push lifter 16 at high speed and generate abnormal noise, which is not easy to use and impairs the sense of quality. Is done. On the other hand, in the lid urging structure A of the invention, since the lid opening angle of the first position is greatly corrected to about 25 degrees, such a problem can be solved or alleviated, and fluttering and tapping sound can be solved. Can be reduced, the feeling of luxury is increased, and it is also effective in preventing finger pinching.

(3) The operation of both link members 4 and 5 is similar to that of the two link members of Patent Document 1, and as the opening / closing locus of the lid 2, the original opening / closing locus of the first link 4 is used by the second link 5. By restricting it, it is modified to be compact, and the lid 2 is controlled so as not to interfere with the outer panel 8 when opening and closing. Further, in this structure, the lid 2 is in the fully open position as shown in FIG. 6B via the first and second links 4 and 5, and the upper side of the first link 4 is the plate 50 of the second link 5. It is in contact with the inside of the shape, and the base end side edge portion of the lid 2 is in contact with the middle plate portion 41 of the first link 4. As a result, the lid 2 is stably held in the fully open position opened at 118 degrees. Moreover, in this structure, in the fully open position, the first link 4 is sandwiched between the lid 2 and the second link 5, making it difficult to see, and the second link 5 is on the space side of the housing 1. The flat design surface is arranged, and the design surface is substantially the same surface (continuous surface) as the rear wall 30 of the base 3 integrally incorporated in the housing 1 and the corresponding portion of the lid 2. It is excellent in appearance due to things such as.

As described above, the lid urging structure of the present invention can be variously modified except for the requirements specified in the claims. For example, the housing 1 has a configuration in which the fuel filler port is arranged inside the opening, but a configuration in which the electric charging port is arranged inside the opening may be used. Further, as the lid 2, although the support 25 is attached to the lid 20, a portion corresponding to the support 24 may be integrally formed with the lid 20. As the base 3, for example, a base corresponding portion may be integrally formed with the housing. The first and second links 4 and 5 may have a configuration in which one end side is pivotally supported on the back side of the lid and the other end side is pivotally supported on the housing or base, and a specific pivotal structure with respect to the housing or base is sufficient. Is not limited to this form and can be designed arbitrarily.
